Jenny Cavanaugh, the ghostly lady of 926 Augur Lane, has enlisted the investigative services of her fellow residents to solve a decade-old murder--her own. Abigail Rook and her eccentric employer, R. F. Jackaby, dive into the cold case, starting with a search for Jenny’s fiancé, who went missing the night she died. But when a new, gruesome murder closely mirrors the events of ten years prior, Abigail and Jackaby realize that Jenny’s case isn’t so cold after all.

Fantasy and folklore mix with mad science as Abigail’s race to unravel the mystery leads her across the cold cobblestones of nineteenth-century New England, down to the mythical underworld, and deep into her colleagues’ grim histories to battle the most deadly foe she has ever faced.

Ghostly Echoes, the third installment in the New York Times bestselling Jackaby series, features its much-loved quirky, courageous characters and sly humor in the scariest and most exciting volume yet.

Pandia(Grade: B+) We finally learn a little about Jackaby's past (and it's sad). There are a lot of other mysteries we discover as well, which sets up future installments. The series seems to have more of a focus now. Not sure where the hinted romance between 2 characters could be going as it seems pretty impossible though.
